A 10kv superimposed heat storage boiler

Abstract

The invention relates to a 10 kV stacked heat storage boiler which comprises a vortex heating furnace, a heat accumulating type heat exchanger, a preheating water tank and a separation water tank frombottom to top. The vortex heating furnace, the heat accumulating type heat exchanger, the preheating water tank and the separation water tank realize heat conduction through heating pipes which are fixedly connected with each other; firstly, the vortex heating furnace heats the heating pipes, then heat storage on the heat accumulating type heat exchanger is carried out by the heating pipes, the preheating water tank is mainly used for storing water, and the separation water tank is mainly used for separating high-temperature water and high-temperature steam; high-temperature steam can performhigh-power heat storage on the heat accumulating type heat exchanger; the heat accumulating type heat exchanger can be used for supplying heat during heating; the heat conduction coil pipe structureof the traditional vortex electric boiler is improved into a vertical pipe structure, the heating of the heating pipes in the middle of the axis is realized by utilizing temperature difference and gravity driving, and the heating is more direct; the separation water tank at the top is used for preventing the heating pipes from being overheated and additionally generating high-temperature steam; and compared with the circulating heat pipe structure, the 10 kV stacked heat storage boiler has higher heating efficiency.

Description

technical field [0001] The invention relates to a 10kV superimposed heat storage boiler, which belongs to the field of electric heat storage boilers. Background technique [0002] Traditional regenerative electric boilers generally use eddy current coils to heat the heat pipe, and the heated high-temperature liquid is transferred to the heat storage body through the circulation tube. Because the heat storage body is generally block-shaped, it is difficult to punch holes, so it is generally It is only by contacting the circulation tube outside the heat storage body to achieve heat conduction, the heating rate and heat removal rate are relatively unsatisfactory, and when heat utilization is required, the change in heat transfer can only be achieved by increasing the flow rate of the pipeline, but the flow rate It is easy to be limited by the cross-sectional size of the pipe, and the heat transfer is relatively limited. Excessive heat transfer rate will easily lead to excessive...
